Obviousness

The provided "Prior art keywords" and "Definitions" sections do not contain specific prior art references (e.g., patent numbers, publication IDs, academic papers) that would be required to conduct a detailed obviousness analysis under 35 U.S.C. § 103. The information describes general concepts and commercial services known as prior art, but does not provide the specific documentary evidence needed to identify combinations of references and motivations for combining them.

The patent itself describes "the one way location sharing prior art," including services like On Star and Mercedes Benz TeleAid, where an aid center can track cars, and commercial services allowing parents to track children. A key distinguishing feature highlighted in the patent is that "None of these services allow the occupants of the car to know where the aid center is or allows the children to know where their parents are". Furthermore, the patent explicitly states that "the prior art kid tracking systems could not be reconfigured in the field to add new individuals with whom location information was to be shared".

The invention, as described, addresses a "need" for a system that allows users to contact rescuers and know the rescuers' locations, and vice-versa, and requires cell phones to be reconfigurable in the field to add "instant buddies" for location sharing.

Without specific patent or publication references for the "one way location sharing prior art" or "prior art kid tracking systems," it is not possible to:

1. Identify concrete combinations of prior art elements.
2. Articulate a specific motivation for a person having ordinary skill in the art to combine those elements to arrive at the claimed invention of US10750310.

Therefore, based solely on the provided information, a full obviousness analysis under 35 U.S.C. § 103 cannot be performed.
